通过测量和激光扫描技术在越南留下遗产

Phu My Port is a general cargo port located in Ba Ria-Vung Tau, Southern Vietnam. Operating since 1993, the port aims to offer a fast, effective and reliable port services available to customers 24 hours a day all year long. When the owners faced challenges in obtaining complete data documentation for the port, Portcoast recommended applying a technique they had used previously: laser scanning to collect data in order to develop a 3D BIM model of the port. The port’s owner commissioned an inspection report for the 132-metre main berth and 72-metre-long access bridge, along with 3D laser scanning of the whole Phu My Port, including yard, warehouses and facilities. By scanning the port and its facilities, the goal was to provide the owners with a digital twin of the whole site for ongoing inspection and maintenance.

该项目的投资者渴望确保一支经验丰富的团队以最高水平进行激光扫描，他们可以明确验证数字双胞胎是否正确。

Portcoast是该地区最有经验的海洋，水路和运输基础设施的测量师之一。他们以准确性的声誉，在该地区执行类似项目时具有可靠的记录，例如附近的3D扫描Hyosung Vina Chemicals端口，Posco SSVN港口及其工作记和港口SITV. In this project, surveyors from Portcoast were responsible for inspecting and scanning the whole port as well as providing quality assurance for the final 3D model.

Requiring both accuracy at speed and range as well as the ability to access narrow, challenging areas, the team opted for a combined reality capture solution, including theLeica Scanstation P50对于远程扫描工作，Leica RTC360and theLeica BLK360. For the topographic survey, surveyors on site usedLeica Nova TS60，，，，Leica GS18TandLeica Icon ICR80大地设备。

Thanks to its range of 1 km and accuracy of 1 mm, the ScanStation P50 was able to capture detailed, accurate data across large areas, fast. Meanwhile, the RTC360 and BLK360 laser scanners captured the isolated and inaccessible areas under the berth where operating a larger tripod-mounted 3D scanner was not viable. The flexibility of these smaller scanners meant the equipment could be securely lowered into place - a technique previously tried and tested when capturing the Hyosung Vina Chemicals port.

虚拟现场访问

由于总面积约为30公顷，因此团队需要从大约一百个位置进行扫描，结合数据并将其迅速转移到现场到办公室。在该地区不可预测且不断变化的热带气候中，数据的快速捕获和传递是必须的。

Based on their previous experience working with the technology, Portcoast again selected theLeica InfinityandLeica Cyclone办公软件充当站点和办公室之间的数字桥梁。只需一秒钟即可传输现场和办公室的数据，团队可以实时查看数据，与现场团队同步工作。

Portcoast的Hoang Hiep博士解释说，“ Leica GeoSystems设备可以帮助我们避免延迟现场数据处理以及使用Leica Geosystems的软件，我们可以在每次需要时检查这些点。有了新的总站和GNSS设备 - 田野和办公室之间的流程是无缝的，帮助工程师减少了两个地方之间的时间。数据的高速和准确性是Leica Geosystems的设备是我们的首选。”

使用数据,Portcoast建立点云莫del for the whole port incorporating all the information from each element into the BIM model. The accuracy of data capture means the user can experience the project through VR/AR. The team is able to carry out quality checks on the locations to inspect details, such as the inclination and rotation angle around the vertical axis of the piles under the berth using the point cloud. Thanks to the precision of the model, the clients and site supervisors can now monitor all the survey data without visiting the construction site.

建造ing a legacy

Not only will the digital twin continue to add value long into the future, but in carrying out this work the team have also built a legacy of expertise in Vietnam. Portcoast’s pioneering approach has meant that several new Leica Geosystems devices, such as the Leica Nova TS60, Leica GS18 T, Leica iCON iCR80 have been used for the first time in Vietnam and Southeast Asia.

The practical experience working with these devices will reduce the operational risk for Portcoast when using them on similar projects in the future, and Portcoast will also pass on their experience through a wider training programme.

Dr. Hoang Hiep of Portcoast commented,“Thanks to the durability and effectiveness of the Leica Geosystems products, combined with the training and support from Leica Geosystems, we have been able to save manpower costs on projects such as this. After the training course, we started using the equipment and are now able to pass this expertise on to others. We are training the whole team to ensure everyone in our company is fully informed about 3D laser scanning. To scan and process data are part of our everyday work at Portcoast.”
